In the adjoining figure, four capacitors are shown with their respective capacities and the potential difference applied. The charge and the potential difference across the $4 \mathrm{\mu F}$ capacitor will be

  

 

The resultant capacitance of the given circuit is

Three plates $A$, $B$ and $C$, each of area $50 {\mathrm{cm}}^2$, have separation $3 \mathrm{mm}$ between $A$ and $B$ and $3 \mathrm{mm}$ between $B$ and $C$. The energy stored when the plates are fully charged is

Two capacitors $A$ and $B$ are connected in series with a battery as shown in the figure. When the switch $S$ is closed and the two capacitors get charged fully, then

Two identical capacitors have the same capacitance $C$. The equivalent capacitance between $A$ and $B$ is

Figure $\left(a\right)$ shows two capacitors connected in series and joined to a battery. The graph in figure $\left(b\right)$ shows the variation in potential as one moves from left to right on the branch containing the capacitors, if

In the following diagram, the charge and potential difference across $8 \mathrm{\mu F}$ capacitance will be, respectively

Find equivalent capacitance between $A$ and $B$

In the adjoining figure are shown three capacitors $C_1, C_2$ and $C_3$ joined to a battery. The correct condition will be (symbols have their usual meanings)
